A case of pilomatricoma on the right temple in an elderly woman

Abstract

A 69-year-old woman noticed a rapidly growing reddish tumor on the right temple about 2months before her first visit to our hospital. An initial physical examination revealed a reddish and slightly hard tumor measuring 14×13 mm. Dermoscopic findings showed a yellowish-white structure with streaks and linear-irregular vessels. Based on histopathological examination, the tumor was diagnosed as a pilomatricoma with a squamous epithelium. Pilomatricoma is commonly observed as a subcutaneous nodule in young patients. It sometimes develops a variety of clinical manifestations such as the protrusion of a tumor. This report summarizes the statistics for the occurrence of pilomatricoma in elderly patients and emphasizes that dermoscopy is useful for the differential diagnosis of pilomatricoma, especially in atypical cases.
